Abstract:
PURPOSE: Right ventricular (RV) infarction is associated with increased morbidity and mortality in patients with acute inferior wall myocardial infarction (MI). A 12-lead electrocardiogram (ECG) has a poor tendency to identify RV involvement. Our objective was to evaluate the diagnostic accuracy of 80-lead body surface mapping (BSM) for RV infarction and to compare diagnostic accuracy of 12-lead ECG criteria and 80-lead BSM for RV infarction in patients with acute inferior wall MI. METHODS: Between September 2002 and January 2003, 96 patients visited to our emergency center with AMI. All standard initial 12-lead ECG and 80-lead BSM were examined and compared with angiographic and echocardiographic findings. RESULTS: Thirty-one patients were confirmed as inferior wall MI. With the use of exclusion criteria, sixteen patients included in this study. RV infarction accompanied in 5 patients of these 16 patients. BSM showed a high sensitivity (60%), specificity (82%), high positive and negative predictive values (60%, and 82%, respectively), and high diagnostic accuracy (75%) in diagnosing RV infarction in patients with acute inferior wall MI. BSM showed increase in the sensitivity for RV infarction from 40% to 60% when compared with the 12-lead ECG. CONCLUSION: The 80-lead BSM is a more useful test in diagnosing RV infarction in patients with acute inferior wall
